Quality Assessment in Endoscopic Retrograde Cholangiopancreatography(ERCP)

This is an investigator-driven, prospective multicenter trial which analyzes the impact of trainee participation on procedure-related outcome (technical success and procedure-related complications). All ERCPs in the participating centers will be documented using a standard report form which will require the attending endoscopist to provide data relating to the patient (age, gender, diagnosis, bilirubin levels) and the procedure (including but not limited to the indication, technical aspects including cannulation technique, time to cannulation, degree of trainee involvement - where appropriate, procedure-related adverse events and their outcome). Because teaching ERCP is not yet a standardized procedure, we aim to assemble a large database, stemming from the experience of several teaching centers in order to identify the main patient and operator-related factors which might influence the outcome of the procedure.
